Sara Caldwell, DVM
Practice Owner
Dr. Sara Caldwell grew up in Atlanta Georgia with her mom and step-dad, one brother and a house full of pets. She is the owner of the practice and its primary veterinarian.  She always wanted to be a veterinarian since she was a little girl rehabilitating tiny birds that fell from their nest and putting pretend casts on her teddy bears.  She is thoroughly fulfilled by relieving the suffering of animals and is honored to be able to do so as a livelihood. She enjoys horses, specifically dressage, although she has evented, foxhunted and played polo.  Her favorite dog breeds tend to be brachycephalic (like pugs and bulldogs) but she has also owned and loved dachschunds, Danes, and heelers. She currently shares her home (and her heart!) with a pug, a Clyde cross horse, and her very sweet small child :)

Megan has loved animals for as long as she could remember. She always knew a career in animal health was her calling. In high school she worked part time at an animal hospital before going away for college. She was certified as a groomer since 2008. After moving to Happy Valley she made the career change to a veterinary assistant at HVVH and absolutely loves it!
In September 2014 Megan married the love of her life, Mitchell. They just recently bought their first house and have a baby on the way in November 2015! They have two pets, a cat named LuLu and a dog named Ifrit. In their spare time they love to go hiking, beach trips, dog parks, etc.

She has three at home but is always looking for more to add to her collection. She’s been a veterinary receptionist for over 4 years and enjoys getting to know clients and their furry companions. In her spare time she likes hiking, reading, and cooking. She lives in Sandy with her boyfriend, cat hoard (Beavis, Brisby, and Vesuvius), and a sweet mini Aussie named Arya.

Ebony has loved animals her entire life and knew that her career had to involve working with them. After spending some time volunteering, she was picked up by HVVH as a Tech Assistant and could not be happier gaining the lab and hands on experience that will further her career.
Currently, Ebony lives in Milwaukie with her boyfriend Justin, their two ferrets (Zoro and Korra) and corn snake (Zuko). She enjoys spending her free time reading, crocheting, cross stitching, watching Japanese anime and playing video games.

Technician Assistant
Tosha grew up in Vancouver, Washington. She volunteered at a horse rehabilitation center when she was in high school. She also worked for a Kennel who shows and breed Lhasa Apso's for almost 12 years. She also worked for Petco as a groomer for 8 years. She loves animals and working with them - it’s always been her calling. She has two beautiful daughters and enjoys spending her free time with them.
Karissa is a Los Angeles girl, born and raised, who recently relocated to Oregon in February, 2015. Her entire life has revolved around rescuing animals in need. From cats and dogs, to goats and horses, Karissa always found herself giving her time to those in need. She now just owns her best friend of 13 years Loki, a German Shepherd mix and Ku, a rabbit she recently rescued here at the hospital. Being that her entire family has history in the equine business and rescuing all types of creatures, it was only a matter of time before she made her dreams become reality in the veterinary field. She has goals to expand her education and career into the large animal medical field, mainly with horses. In her spare time she loves to have quality time with Loki, volunteer whatever time she can at local barns, and explore Oregon's scenery.
